Hi,
I want to simulate the isolated rotor modes wherein the tower-nacelle subsystem is fully rigid. I want to check the case, for an isolated rotor spinning in a vacuum, progressive and regressive modal frequency curves are symmetric about the corresponding collective modal frequency curve.
When I do this simulation, I just change the feature flags in the .fst file. I enable FlapDOF1, FlapDOF2, and EdgeDOF, and disable TeetDOF, DrTrDOF,GenDOF, YawDOF, TwFADOF1,TwFADOF2,TwSSDOF1,TwSSDOF2,CompAero and CompNoise.
and keep all of other parameters unchanged, then do the linearizaiton.
Is this simulation correct? Has anyone done this case before?
Thanks.
